Configurable Customer Control System: Diagnosis Saturn Outlook I

DIAGNOSTIC CODE INDEX

DIAGNOSTIC CODE INDEX

Diagnostic Starting Point - Secondary and Configurable Customer Controls

Begin the system diagnosis with the Diagnostic System Check - Vehicle . The Diagnostic System Check - Vehicle will provide the following information

1. The identification of the control modules which command the system
2. The ability of the control modules to communicate through the serial data circuit
3. The identification of any stored DTCs and their status

The use of the Diagnostic System Check - Vehicle will identify the correct procedure for diagnosing the system and where the procedure is located.

Diagnostic Instructions

1. Perform the «Diagnostic System Check - Vehicle»(ref-301168-S23293457462008101700000) prior to using this diagnostic procedure.
2. Review «Strategy Based Diagnosis»(ref-301168-S03565209752008101700000) for an overview of the diagnostic approach.
3. «Diagnostic Procedure Instructions»(ref-301168-S33120892802008101700000) provides an overview of each diagnostic category.

Conditions for Running the DTC

Ignition ON.

Conditions for Setting the DTC

BCM detects voltage above 18.5 volts for 100 msec.

Action Taken When the DTC Sets

BCM will ignore the switch command.

Conditions for Clearing the DTC

1. The condition for setting the DTC is no longer present and the DTC is cleared with a scan tool.
2. The BCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive ignition cycles.

Visual/Physical Inspection

1. Inspect for aftermarket devices which may affect the operation of the Steering Wheel Controls System. Refer to «Checking Aftermarket Accessories»(ref-301170-S32217293102008101700000) .
2. Inspect for easily accessible or visible system components for obvious damage or conditions which may cause the symptom.

Symptom List

Refer to Steering Wheel Controls Inoperative in order to diagnose the symptom.

1. Perform the «Diagnostic System Check - Vehicle»(ref-301168-S23293457462008101700000) prior to using this diagnostic procedure.
2. Review «Strategy Based Diagnosis»(ref-301168-S03565209752008101700000) for an overview of the diagnostic approach.
3. «Diagnostic Procedure Instructions»(ref-301168-S33120892802008101700000) provides an overview of each diagnostic category.

Diagnostic Aids

1. If a single switch function is inoperative, test the suspect switch.
2. The resistance value for the individual steering wheel control switches (right) should be within the listed resistance values below

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the right steering wheel control switch.
2. Ignition ON, test for ignition voltage between the ignition circuit terminal 3 and ground. If greater than the specified value, test the ignition circuit for a short to voltage. If the circuit tests normal, replace the BCM. If less than the specified value, test the ignition circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM.
3. Verify the scan tool SWC Bank 1 parameter is Idle. If not the specified value, test the signal circuit terminal 4 for a short to voltage. If the circuit tests normal, replace the BCM.
4. Ignition OFF, connect the harness connector at the right steering wheel controls switch assembly.
5. Ignition ON, while pressing and releasing each of the right steering wheel control switches, observe the scan tool SWC Bank 1 parameter. The SWC Bank 1 parameter should display a value corresponding to SW 1 - SW 10 for each of the right steering wheel control switches pressed. If not the specified value, test the signal circuit terminal 4 for a short to ground or an open/high resistance. If the circuit tests normal, test or replace the right steering wheel controls switch.
6. If all circuits test normal, test or replace the BCM

Component Testing

1. Ignition OFF, disconnect the harness connector at the right steering wheel control switch.
2. Test for infinite resistance between the ignition terminal 3 and the signal terminal 6 with the switch in the open position. If less than specified value, replace the switch.
3. Test for less than 5,400 ohms between the ignition terminal and the signal terminal with the switch closed in each position. If greater than the specified range, replace the switch.
